CVE-2024-26466Network attack vector

JavaScript execution via URL fragment passed to eval

Published Feb 26, 2024 · Updated Oct 30, 2024

DOM-based XSS in web-platform-tests/wpt before commit 938e843 allows remote attackers to execute JavaScript via a crafted URL. Range-test-iframe.html evaluates the URL fragment with eval() when testRangeInput is undefined, treating fragment text as executable code. A victim must open the crafted page in a browser; execution occurs in the test suite's origin and permits page-context data access or modification.
